Kirkpatrick for The New York TimesDid a lab leak cause Covid?U.S. lawmakers opened hearings yesterday into the origins of the coronavirus pandemic. The hearing, which quickly became politically charged, underscored how difficult it may be to ascertain the origins of Covid-19.Republicans on the House panel investigating the pandemic’s origins made an aggressive case that the virus may have been the result of a laboratory leak. The lab-leak hypothesis recently gained a boost after new intelligence led the Energy Department to conclude, albeit with low confidence, that a leak was the most likely cause.The first public hearing came as the debate intensifies about one of the great unsolved mysteries of the pandemic. The committee is made up of seven Democrats and nine Republicans, including Representative Marjorie Taylor Greene, who is known for her embrace of conspiracy theories.Here’s what we know, and don’t know, about the origins of the pandemic.Two theories: The lab-leak hypothesis centers largely around the Wuhan Institute of Virology, which studied coronaviruses. But some scientists say the virus most likely jumped from animals to humans at a market in Wuhan, China.Stakes: A lab-leak consensus could further roil U.S.-China relations.Related: Starting tomorrow, the U.S. will no longer require a negative test for travelers from China.Protesters with flags from Georgia, Ukraine and the E.U. outside Georgia’s parliament building.Zurab Tsertsvadze/Associated PressProtesters in Georgia chant ‘No to the Russian law’Thousands of demonstrators marched toward Georgia’s Parliament yesterday, a day after a bill on “foreign agents” passed first reading. Critics say the measure would replicate legislation in Russia that has been used to restrict civil society.Last night, a group of protesters tried to storm the government building, but were repelled by police officers who used water cannons, stun grenades and tear gas. On Tuesday, riot police officers had also used tear gas and water cannons to disperse a large rally in Tbilisi. Waving Georgian and European flags, the protesters chanted, “No to the Russian law!” as they walked down the main avenue in Tbilisi.The country’s pro-Western opposition sees the bill as following the model of Russian legislation passed in 2012, pushing the country closer to Moscow and highlighting democratic backsliding. Under the measure, nongovernmental groups and media outlets that receive more than 20 percent of their funding from a “foreign power” would be required to register as “agents of foreign influence.”What’s next: The bill, backed by the governing Georgian Dream party and the prime minister, was expected to be approved. The president said she would veto it, but the governing party has enough votes to override the veto.In just the Rajouri district, about 5,200 volunteers are being rearmed.Atul Loke For The New York TimesIndia arms Kashmir villagersThe Indian government has started reviving local militias in the Muslim-majority region after a series of deadly attacks on Hindus. The strategy casts doubt on the government’s claims that the region is enjoying peace and prosperity, nearly four years after India revoked its semiautonomous status.Over the past several months, there have been repeated attacks on civilians in the Jammu part of Kashmir, one of the world’s most militarized places.
